The necessity of antibacterial

Japan has a warm climate and a lot of rainfall. Especially in the summer, it continues to be hot and humid. Bacteria (microorganisms) are prone to mass reproduction, causing food to spoil and cause food poisoning. Daily necessities in the living environment are also polluted.

Japan has known and used many natural materials with antibacterial effects since ancient times. Such as eucalyptus, because of its high antibacterial effect, long-term use is not easy to rot, so it has been used in the basic materials of the house and other important parts. In addition, Tongmu is also used to make wardrobes to protect clothes due to its good antibacterial properties.

The beautiful lacquerware that people use every day and the copper plate of the roof are not only aesthetically pleasing, but also their excellent antibacterial properties.

Microorganisms begin to multiply in an exponential manner in a suitable environment.

For example, E. coli can reach 100 million E. coli in 9 hours after the growth of three elements (temperature, moisture and nutrients), which is as high as 108 times. On the other hand, if the breeding conditions are controlled, the growth and reproduction of bacteria can be inhibited. Therefore, the concept of antibacterial refers to a technique that can suppress bacterial growth well.

) various antibacterial methods

Various means of inhibiting bacterial growth that we use in our daily lives:

Reduce the temperature (refrigerator and frozen food)

) Reduce moisture (dry products, dry foods)

Adjust the osmotic pressure (salted products such as salt and sugar)

) Limit oxygen supply (canned, vacuum packed)

) Control pH (sushi, western pickles)

Use antibacterial agents

Antibacterial technology using antibacterial agents has developed rapidly in recent years. The use of antibacterial agents can inhibit the growth and development of bacteria and fungi under conditions suitable for bacterial growth. Table 3 shows three types of substances that inhibit bacterial growth.

Antibacterial materials have their own advantages and disadvantages depending on the type. In terms of "stability and effect", inorganic systems, especially silver-based antibacterial agents, have the advantages of high efficiency and safety.

As we all know, silver is a stable metal. Since ancient times, people have known that "silver tableware" has an antibacterial effect and can be safely used, but its only problem is that the cost is too high. Despite this, silver is still widely used in "antibacterial" and "moldproof" products due to its excellent antibacterial effect. Fig. 4 is a comparison of various antibacterial agents, and Fig. 5 is a comparison of antibacterial effects of various metal ions.

) Popularization of antibacterial products

Years ago, the proliferation of antibacterial products made from various antibacterial materials set off an unordered "antibacterial tide", which caused strong criticism from all walks of life. After that, the industry has undergone serious reflection. The current Japanese antibacterial community follows the principle of “use effective antibacterial products where needed”, thus enabling the antibacterial industry to develop steadily.

Development policy of antibacterial products technology conference

1 Improve the quality of life and level from the interests of consumers

2 Reduce environmental burden, popularize and develop antibacterial products coexisting with microorganisms

3 self-responsibility and self-certification

4 disclose security and quality information

5 popular use of antibacterial products

Establishment of the antibacterial product technology conference

With the popularization and application of antibacterial products, a large variety of antibacterial products have flooded into the market, and related product standards,

For example, antibacterial properties and methods of use have not yet been established, which has caused serious dissatisfaction among consumers, and public opinion has also slammed it. In this context, in 1993, Japan established the "Inorganic Antibacterial Agent Research Society for Silver (Silver Anti-Research)", and its main members are mainly manufacturers of inorganic antibacterial agents. In June 1998, based on the "Silver Anti-Research", it also absorbed more antibacterial products, antibacterial agents and related famous experts and scholars, and formally established the current "Antibacterial Products Technology Conference".

The purpose of the antibacterial product technology agreement is to develop relevant product standards and test methods from the perspective of protecting consumers' interests, to ensure the safety of antibacterial products and antibacterial agents, and to provide for the majority of users and consumers. High quality and excellent products.

Work according to the above five concepts. The specific work is as follows:

·Standards on quality and safety

·Standards about login quality and security

·Special terminology for antibacterial and antibacterial agents

·Regulations on the use of the SIAA logo

· Specify the scope of responsibility of antibacterial products and antibacterial agents

·Protect the responsibility of antibacterial testers, etc.

The above specific content is formulated to promote a viable and self-management system for antibacterial products. At the same time, in order to ensure the transparency and fairness of the antibacterial industry, we have also done the following work:

· Conducted market research on antibacterial products circulating in the market

· Promote information exchange between various groups in the industry. In addition, in order to make antibacterial products popular in consumers and related industries, we have done the following work:

· Hold related lectures, seminars, symposia, etc.

· Open and exchange of information on the homepage of the Antimicrobial Products Technology Association

Work characteristics

The main features of the antibacterial product technology conference are as follows

Application of industry standards for quality and safety

The emergence of industry standards: from July to December 1998, sponsored by the Ministry of Industry, Industry and Industry, the relevant experts, representatives of consumer groups, representatives of anti-bacterial related industry groups and this agreement will participate in the event A seminar on the association of new functional products, the meeting discussed a set of benchmarks: "antibacterial product benchmarks." Focusing on this content, and after repeated and careful discussions, the current "industry standards" have been formulated.

The new content is divided into three areas:

Quality Standard

This agreement will establish the antibacterial performance standards based on the definition of antibacterial and antibacterial processed products to ensure the quality of the products. At the same time, due to the need for continuous effectiveness of antibacterial products, this protocol will apply different antibacterial performance persistence experiments (water resistance, light resistance, etc.) according to different product use conditions and uses. Based on the above objectives, we have established the following standards:

Antibacterial performance standard for antibacterial agents

The "minimum inhibitory development concentration (MIC)" or "minimum bactericidal concentration (MBC)" antimicrobial performance criteria were determined based on the type of antimicrobial agent.

The antibacterial performance standard of the antibacterial product is based on the "antibacterial force test method" I (film method) "or" antibacterial force test method III (light film method), and the difference between the increase and decrease values ​​is 2.0 or more.

* This standard is changed according to the JIS standard after the Japanese Industrial Standards (JIS) has established antibacterial standards.

3SIAA tagged application

To ensure the excellent antimicrobial and safety performance of antimicrobial products, we have established the above industry standards, and in order to make it easy for consumers to identify and to facilitate the implementation of standards, we have established the SIAA logo.

1 safety standard

It is very important to balance the safety of the antimicrobial agent with its antimicrobial properties. Some antibacterial agents are highly safe, but if the amount of addition is increased due to poor antibacterial effect, safety problems may occur. Conversely, antibacterial agents with low safety may be safely used due to their low added amount. Therefore, we ensure the safety of the antimicrobial agent by specifying the maximum allowable amount of antimicrobial agent and not allowing certain chemicals to be used in the antimicrobial agent. The following provisions are formulated in the standard:

Antimicrobial safety standard

The following four tests were strictly carried out: "Acute oral toxicity test", "Skin disposable stimulation test", "variation test", "Skin sensitivity test".

Safety standards for antibacterial products

There are the following requirements for antibacterial products: "The concentration of the antibacterial agent should be lower than the concentration of the safety test", "an antibacterial agent that has passed the antibacterial safety test."

Develop safety data sheet (MSDS) for antimicrobial products

The meaning of the logo and how to use it

It is an abbreviation of English Self-Imposed Authorization for Antimicrobial-article (meaning self-certification of antibacterial products). The member companies of the Antibacterial Products Technology Association are responsible for the use of antibacterial products and antibacterial agents that meet the antibacterial standards set by the Antimicrobial Products Technology Association. The SIAA logo indicates that it is a symbol of reassurance and trust that consumers recognize. Enable consumers to have a concise and reliable logo representation when selecting a product. The logo was officially used on December 17, 1988. Only the official members of the "Antimicrobial Products Technology Association" can use this logo, and this Council strictly supervises the use of this logo in the market.

Method of identification

The product shall also indicate the type of antibacterial agent used, the processing method, the processing location and the description of the SIAA logo, while indicating the design designation specified by the Society. The type of the antibacterial agent is one of the following, an inorganic antibacterial agent such as silver, a natural organic antibacterial agent, a synthetic organic antibacterial agent or a photocatalytic antibacterial agent, and the processing method is one of the following, directly added, fired, Painted or printed, the processing part is one of the following, the whole, the surface, the inner surface or the part.

Figure 7 shows the SIAA antibacterial logo

Development of antibacterial product technology agreement and antibacterial JIS (Japanese Industrial Standard)

The Association has been carrying out various tasks in accordance with the "Antimicrobial Products Standard" and "Industry Standards". With the progress of the preparation of the national standards for the antibacterial-related industries, the antibacterial JIS standard (JIS Z 2801) and the JNLA system (the system for the identification of the laboratory) have been implemented since 2001. The antibacterial JIS standard was established by the Ministry of Economy, Trade and Industry of Japan and is the first national standard for the antibacterial industry. With the implementation of antibacterial JIS, the antibacterial performance test and antibacterial effect determination in the industry standard are based on the JIS standard.

The development of this association and the formulation of JIS standards

The antibacterial product technology agreement was established in June

July-December assisted in planning "antibacterial product benchmarks

The industry standard was established in December, and the SIAA logo was used.

From June to July 2000, the Bureau of the Council was entrusted to develop a JIS draft.

From October to October 2000, the Bureau of the Council was entrusted to develop a JNLA Skills Program.

JIS public release on December 20, 2010

On December 20, the testing organization began the JNLA application

In July, JNLA began to identify testing institutions.

(After April 2002, a total of 7 institutions passed the certification)

In August, the JIS antibacterial SIAA logo was implemented.

Research and development of standard test strips for JNLA from August to March 2002

Summary of JIS and JNLA systems

JIS related to antibacterial has the following two aspects

1 JIS standard: The JIS standard "JIS Z 2801" for antibacterial aspects is composed of the antibacterial performance test methods and the antibacterial effect judgment standards of all antibacterial processed products. The test method is based on the filming method of the Association (the fiber product is based on the quantitative test method of JIS L 1902), and the product obtained after the test has an antibacterial activity value (difference value difference) of 2.0 or more, which is called "antibacterial processing". "Products", this is the latest JIS judgment standard.

2 JNLA system: a system closely related to the above JIS standards, through administrative review of testing institutions

3 (Using the antibacterial skills program developed by the Association), the qualified person is certified to prove that the testing organization has passed the JIS regulations. The test report of the testing organization is marked with the JNLA logo.

JIS system and this agreement

1 The meaning of JIS: Products that do not meet the JIS antibacterial standards will be withdrawn from the market. A few years ago, "antibacterial boom" problems and ineffective antibacterial products, such as: only the "addition of antibacterial agents" logo products, will not be selected by consumers in the future

2 The status of this agreement in JIS

The Association assisted and supported the development of the “Antimicrobial Product Benchmark” and, based on this, assisted and supported the planning and formulation of the JIS and JNLA systems. After the full implementation of the JIS and NLA systems, the Association fully accepted its contents and, based on this, revised the rules and standards of the Association.

3 SIAA logo and JIS relationship

The products identified are those produced by the quality management process in accordance with the “Antibacterial Products Standard” and JIS standards as defined by this Council. The significance of the SIAA logo is: 1. It is easy to identify as an antibacterial product mark; 2. In addition to complying with the “antibacterial product test method” and “antibacterial performance judgment standard” as stipulated in JIS and industry standards, the SIAA logo also indicates that it meets the requirements of product performance. "Persistence of antibacterial effect", "safety standard for products" and "representation of SIAA logo", so that consumers understand that products indicated by SIAA are products that can be purchased with confidence.

,to sum up

With the formulation and implementation of anti-bacterial national standards, the chaos of the past has been changed, and the antibacterial products market has developed in a standardized and orderly direction.

The use of antibacterial technology is very important for consumers. Therefore, it is very important to discuss the effectiveness and safety of antibacterial products from the perspective of consumers and to disclose such information.

The Antimicrobial Products Technology Association is an independent civil society that operates solely on the membership fees of its members and all its work is supported by the members' free contributions. In the future, this Council will continue to stand on the side of consumers and carry out various tasks for the purpose of properly spreading antibacterial technology and antibacterial products in Japan.

The above is the market trend of the Japanese antibacterial industry and the work content of this association, hoping to play a reference role in the development of China's antibacterial industry.
